To ali whom it may concern.

Be it known that we, FRANK PrNinend om PAXTON PETTY, Subjects @fins Majesty the King of Greet Britain, nid residing :it lill Commercial reed, lortsinouth, llafinphire, England, and 104 Kendrieizyroed,

Reading, Berkshire, England, respectively,

'chunping parts of ther binders or holders so that any particular sheet or sheets can he readily removed or e new sheet or sheets inserted, the sheets beingr provided with slotted holes 0r openings for permitting engagement therewith of posts, cords, thongs,lor hands provided in connectionwith` the binders or holders for the purpose of rrever tingfnnintentionel displacement or dei rchniirit ni the sheets when therleinping ports or ha; r are wn eport. rlhe principal objet of the present invention is, in e temporary hinder tir-'loose sheet holder whereof the chimp infr parts eredi-:mn together hy wind ing up or drowi'ng out one orniore flexible Connections' which is or ein attached to l oth clamping 'ports i'to-provide for engaging the loose sheets and maintaining those neatly and in proper position all in register in the binder, ineens separate from the flexible connections serving to pull the elainping parts together, es we have found by extended experiments that it is practically impossible to nmintnin the sheets neatlyY in register by fastening these upon the seid .flexible connections, and relyingT upon the letter only, to hoop the sheets exsdly overeoch other :it all times.

For this purpose our invention consists in providingr the hinder with two or more leather strati s or the like, e. g., 'lexihle thongs oi,E suitable materiel, which teilig;` secured et one end ore passed through openings in the two clamping;` parts of the hinder and then into one oi the covers proper, which is inode hollow for the purpose, sind in'which the other ends oli' the llexihle thongs ere left quite free. ln this wey, we are fihle to pro- 'vide l'nr more relatively rigid mea-ns for en gaining the slotted openings in the loose sheets than can he provided hy' the seid lloztilole connections ol the clamping parts, Owing to the i I l function of snch ilexihle connections in their cooperative relation with'the ineens, sneh es a screwed rod ind nut, for drawing the clenipino; parts together.

. '1" o ineke our inten tion clearly and readily understood, we will describe the seine with reference to e forni of binder in which the clamping parts are drawn together by e ilexihle length of webbing, ete. tightened by e nut and screw dernl A binder of this kind is shown ,in the nceoinlieny'ing drawings with ourimproved sheet engaging ineens ernbodied therein, Figure l being e perspective View of the hinder; lig. 2 o sectional View ot the clamping; bers; 3 eltransrerse section teilten upon the line x lfig. 2', 4 it partiel. front View of tho clamping bers g ig. e Ver-- tical section of the hinder; Fig. 6 e rear view vof the hinder, end Fig. e View or e corner of one of the sheets showing the openings ior engaging the flexible thongs and for providing' a passage for the l'loxilile connections.

The hinder shown. eonsists of clernpinB l: ers e end I) formed of ehennelor trough seem tion :ind terminating in end welle c c and provided with reniovsrhly oonneeted'eoverplatos d. The end wells e c ot the clamping er y (hereinafter termed the upper clampi ing,n har) forni hearings lor o threaded shaft e which is mounted in the har o end has threaded 'thereon block or slide y" fitted within the said lror a so that Upon the rots- Ation ol the shalt c it will move longitidinellj; of the lnr eocordinff to the direction of rotetion ol' the shaft. To this liloel or slidefin the exemple ,ilh strdtcd ere connected the ends of :1- length of tape, richting, leather strep, chain, wire, cot-gnt, or edrivelent ilexihle length or strip f1, which :is shown passes straight out along the nel d over en. miti-friction roller y, through oppositelg,q situated slots 7i /t foi-ined in' the cover-pleins d towards the ends ol' the here e end "o, then. over onli-friction rollersii t in the lier l), thi-e1' gli oppositeljy situated slots li? )t3 lornied in the cover platos towards the other ends of the two lxziis, over iin enti-friction. roller and straight ont :dong the lzor L ronnd en. antieliriction roller g1, located ndi roller g, haelt to the slide or hloelf. ll/'1th such en arrangement, which we are :tw here already lzec'orne known and therefore is not,

:meent to the i.

will draw the tape or webbing or equivalent lengthv f1 strai ht out along, or longitudinally of the bar a, t ereby shortening the distance between the rollers g, 'i and j, i and so ulling the clamping bars a and b towards eacii'other until the sheet or sheets placed between the bars are securely` gripped therebetween. When however it is desired, to insert or remove a sheet or sheets, a reverse rotation of the shait e will cause the slide or blockf to be moved along to the right (rig. 2) and there` by allow the bars a and b to be retracted one from the other a distance corresponding to the decrease inv the distance between the slide or blockf and the rollers g, g1. Now according to our invention we do not fasten the sheets upon those parts of the tape, webbing, or equivalent f1 which extend from one clamping bar to the other, but provide separate means consisting of flexible thongs secured at one end only for thispurpose. As shown in lig. 5 we provide two or more leather straps or the like c which may conveniently be connected to the lower cover proper Z which is hinged 'gto the bar b, the straps or the like passing up through slots m and n in the lower` clamping bar b and coverplate d respectively, and slots o and p in the cover-plate d and upper clamping bar a respeetively, into the, upper hollow cover proper Z1, hinged to the bar a, by way of openings Z2 formed in the frame thereof, the straps or the like working quite free in the cover proper Z1 as the upper clamping bar is raised or lowered relative to the lower clamping bar. In this way it will be obvious how we are able to provide a i'ar more relatively rigid holding of the sheets than is ossible with the iiexible connections of the c amping parts, and consequently in a binder according to our invention thc sheets are held exactly over each. other at all tilnesa Fig. 7 illustrates part of a sheet adapted by slots or openings such as l] to be engaged by the straps or the like 7c, and by slots or openings such as r to provide clearance for the tape, webbing, or equivalent f as this passes from one bar to the other.- It is not how-l ever essential that the tape or the like f1 passes through the sheets as in the example shown. This or these may pass from one bar to thevother clear of the roar edges of the sheets if desired.

From the toregoi ng it will be clear that the essential point ol' ou'r invention lies in the loose ended flexible thongs constituting means, separate from the flexible connections of the clamping parts, for engaging and holding the loose sheets in such manner that at all times they are maintained exactly over each other or in register.

We may in constructing the binder dctacllably connect the Ilexible connectors to I the lower; clamping bar, so that when the connectors have been slightl slackened by rotation of the threaded sha t in the proper direction, they may be detached from the lower clamping bar so as to allow the upper clamping bar and cover proper to be instantly raised to any desired height. To re-secure the binder again all that would be necessary would be to replace the clamping bar and cover proper against the sheets, re-attach the connectors and tighten up these to draw the clamping bars together.

In some eases, the'bi'nders ma be constructed with the covers arrange separate and distinct from the clamping arts so as to be secured therebetween in sni ar manner to the sheets themselves, or in lieu of the covering for the clamping bars and the covers forming the hinge connection therebetween as shown, we may find it more convenient to hinge'the covers proper to the clamping bars in other ways, vfor instance, we may pivotally connect extensions or hinge ieces of the covers proper to the clamping ars.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent is zl. A temporary binder, comprising in combination clamping bars, a hinged cover appropriated to each clamping bar, engaging and register-maintaining means for the sheets consisting of flexible lengths engaging openings in the sheets, and having one en fixed to one of the covers and the other end free, and extending through both clamping bars, said free end passing loosely into the other cover, and means for drawing the clamping bars together to grip and hold the sheets securely therebetween without hindrance to the opening and closing of the covers substantially as herein described.

2. A temporary binder, comprising in combination clamping bars, a hinged cover appropriated to each clamping bar, engaging and register-maintaining means for the sheets consisting of iiexible lengths engagin openings in the sheets and having` one en iixed to one ofthe covers and the other end free, and extending through both clam ing bars and loosely into the other cover, a exible connector connectingthe clamping bars, and means for tightening the connector to draw the clamping bars together. l,

In testimony whereof we have signed our names to this specification in the presence of' two subscribing witnesses. t
